It is configured to provide voltage clamping across the strain gauge outputs as well as the excitation voltage from the signal conditioner. A low capacitance connection to earth helps to avoid earth loops, whilst providing a reliable current path under transient conditions.
The ILC36V load cell surge protector is designed for use with load cells using four wire or six wire connections to a strain gauge bridge. It is installed in series with the line to be protected.
